Abstract: 1289421 Electromechanical resonators; telephone tone generators STANDARD TELEPHONES & CABLES Ltd 23 March 1971 7542/71 Addition to 1277614 Headings H3U and H4K [Also in Division G1] In an electromechanical resonator of the kind disclosed in parent Specification, a sheet of dielectric material 4, Fig. 5, is placed in contact with each electrode 2. The sheet may be on the side of the electrode facing the vibrator element, or on the other side. If the sheet is permanently polarized, an external bias is unnecessary. The vibrator element may have a significant temperature coefficient of expansion for use as a temperature sensor (see Division G1), and one embodiment thereof derives its bias from an electric field in which it is located. The resonators may be used in telephone tone genrators as below. Suitable dielectrics for permanent polarization are polyester, polycarbonate or fluorocarbon films. Resonator construction.-A vibrator element 1 is supported at one or more nodal points, e.g. at an end as in Fig. 5, and vibrates in bending oscillations due to electrostatic forces caused by an A.C. voltage G1 between itself and a fixed electrode 2. A sheet 4 of a dielectric material is located on the electrode. The vibrations cause charge to flow in and out of the capacitor formed by the element 1 and electrode 2, and an output voltage appears across the load R3-C OUT . To prevent frequency doubling, and to provide voltage gain, a bias voltage is applied to the element 1 or to the electrode 2 by a battery or by permanently polarizing the sheet 4. Various combinations of one or more vibrator elements with one or more electrodes are described, and electrical and/or mechanical interconnections may be made to provide a desired frequency response. The preferred range of operation is 1-30 kHz. The element may be a strip, rod, disc or ring. Constructional details are also given in the parent Specification. Tone generation.-Fig. 14 shows eight vibrator elements, each with one electrode, arranged in two groups of four. The elements 16A, 17A 18A and 19A have resonant frequencies of 697, 770, 852, and 941 Hz, and elements 16B, 17B, 18B and 19B resonate at 1209, 1336, 1477 and 1633 Hz. A 4 x 4 matrix of switches, e.g. touch sensitive switches using bipolar transistors or MOSFETS, selects any two of these resonators to give a unique output tone. An " OR " gate system may be included to prevent unintended selection if two switches are activated simultaneously. The output of each group of resonators is detected by an electrode 26 and amplified, part of the signal being fed to a line 22, and part to the resonator inputs 28 to sustain the oscillations of the selected resonators. A more compact layout is described, Fig. 15 (not shown), and also an embodiment having two output electrodes, Fig. 16 (not shown). The latter arrangement allows the line 2 to be separated from the oscillator circuit so that the oscillator is independent of line impedance. The second electrode may also be used to allow the dialling signals to be monitored.

Abstract: 1290903 Detection of a substance by spectral absorption MULLARD Ltd 18 Nov 1969 56362/69 Heading G1A In a method or apparatus, for determining the relative amount of a substance present in a transparent medium, a beam of radiation is passed through the transparent medium and the beam comprises a first and a second mutually perpendicular plane polarized beam component, the first beam component having a narrow band of frequencies lying within a radiation absorption band of the substance and the second beam component having a further band of frequencies which are substantially unabsorbed by the substance. The planes of polarization of both said components are rotated so that the planes of polarization alternate between two substantially perpendicular orientations and so that they may be selectively passed through the medium, the relative intensities of the components being measured and compared to provide an indication of the amount of the substance present in the medium. In an embodiment, Fig.1, a beam of infrared radiation from a source 4 is split up into the two kinds of components 10, 11 specified above, by means of lens 5, polarizers 6, 7 and appropriate filters 8, 9. The beam components 10, 11 are directed on to an yttrium iron garnet (YIG) 12 which is located in a magnetic field determined by an electric current of square wave form; thereby effecting the alternating of the planes of polarization, so that respective components are passed into sample cell window 16. The sample cell window is in the form of a radiation guide in which radiation passing therealong is repeatedly totally internally reflected at the sides of the guide, as shown. The beam components pass through the cell to a further window 18. The intensities of the two components are detected by a photo-conductor 19; the output from the detector 19 being demodulated in synchronism with the waveform 22 to provide an output display 20 which is representative of the reduction in the intensity of the first beam component due to absorption by the substance present in the cell 1. A schematic circuit arrangement for performing the invention is included in the description.
